Can someone just break it down for me? So, I can learn from it and not just get a answer

which graph ??
Answered by

One graph is (-3, 7) the other is (0, 8) the other is (3,7) and the last on is (0, 4)

You must know the properties of lines written in the form y = mx + b
m is the slope of the line and b is the y-intercept
so for y = -x + 4
that line should have a slope of -1, it should lean to the left making an
angle of 45° with the x-axis
it will have a y-intercept of 4
do the same with the other line, it should have a slope of 1/3
look for a line with has a rise of 1 and run of 4
It will have a y-intercept of 8.
Look for such a graph in your test, worksheet, book or ....

as of January, 2023, here are the answers for the Systems of Inequalities Unit test (Unit 7, lesson 8)
I'm pretty sure the answers are in a different place for every person, so I put the answer it was on for me, then a description of the answer
1) (A) or the one with the intersection(point) labeled (-3,7)
2) (B) or the one with the intersection(point) labeled (-3,-8)
3) (C) or the one that says "Infinitely many"
4) (D) or the one that says "None"
5) (C) or the one that says "Infinitely many"
6) (D) or the one that says "None"
7) (B) or the one that is shaded on the right side from the point (3,0)
8) (B) or the one that is shaded below the point (0,-2)
9) (A) or the one that is a small shaded right triangle
10) (B) or the one that says "3 months"
11) (A) or the one that says ".50 per cookie, 1.25 per brownie"
12) (B) or the graph that says "No solutions" under it
13) (B) or the graph that says "Infinitely many solutions" under it
14) (B) or the one that's says (-2.5,-7)
15) (D) or the one that says (5,1)
16) (B) or the one that say "750 T-shirts"
17) (B) or the that says " 28 mL of 5%, and 14 mL of the 65%"
18) (B) or the one that is shaded on the right side and goes through -4
19) (C) or the one that is shaded above and to the left more
20) (A) or the one that is shaded above and has a y intercept of 20
21) (B) or the one that is shaded in-between the bottom crossing area
22) (D) or the one that is shaded to the left of the X
23) (D) or the one that says "y<=x+8 and y>=-3x-8"
Goodluck, if your test doesn't match mine, just use Desmos, it got me through like 90% of these questions
